A patent allows you, and only you, to profit from your genius when you invent something new. No one else can manufacture or sell your invention unless you give permission. However, this protection does not last forever. Depending on what youâve invented, your patent will expire in either 14 or 20 years. When this occurs, anyone can copy your idea and market it.
